I was born and raised in San Antonio and I'm very social and like to go out with my friends and family when I'm not working or attending school. I'm looking forward to graduating with a Bachelor of Science in Nursing with inspiration from my mother because she was also a nurse and for being able to make a difference and help people.

Experiences:

I'm currently a freshman at San Antonio College studying Biology and Nursing.

I used to be an Installer and Team Lead of Decorative Flooring for three years. My job entailed commuting to and from Austin with a crew and floor installation.

I'm now employed at Topgolf as a Bayhost or server which includes taking orders and keeping bays clear and clean.

The four Biochemicals are the building blocks in which life is formed, and consist of carbohydrates, proteins, lipids, and nucleic acids. Since I will be going into the medical field as a nurse it is important and essential for me to know these processes for form a better understanding of normal bodily functions, cellular processes, and metabolic pathways. It will also help me understand how the body works in its natural state as well as its diseased state and to be able to tell the difference so I can help my patients get better and to educate them.

Monomers: Monosaccharides

1) Pentose Sugars

Deoxyribose
Ribose

2) Hexose Sugars

Glucose
Fructose
Galactose

Examples:

Disaccharides- Sucrose (Glucose+ Fructose), Lactose (Galactose + Glucose), Maltose (Glucose + Glycogen)

Polysaccharides- Glycogen (storage for animals), Starch (storage for plants) and cellulose (cell wall structure)

Carbohydrates

Function

Energy source and provides some cellular structures.

Dimers: Disaccharides

Sucrose
Lactose
Maltose

Polymers: Polysaccharides

Starch
Glycogen
Cellulose

Monomers: Amino Acids

Acid group- COOH

(carboxyl group)

Amine Group- NH2
R Group- distinguishes amino acids from one another

Protein Structure: Protein folding

1) Primary Structure:

Long chain of amino acids

2) Secondary Structure:

Helix- coil/spiral

Pleated sheet- accordion folds

3) Tertiary Structure:

Secondary structures folded into each other

Proteins

Functions

Structural
Transport
Movement
Defense
Catalysts

Dimers

Peptides

Polymers

Polypeptides

Lipids

Triglycerides (Fats and Oils)

Functions- Energy source and storage, insulation and protection

Structure- Glycerol +3 acid tails

Saturated- No double bonds, solid at room temperature, and raise LDL

Unsaturated- double bonds, liquid at room temperature

Phospholipids

Function- Major cell membrane component

Structure-

Polar head: hydrophilic, phosphate containing group
Non-polar tail: hydrophobic, two fatty acid tails

Steroids

Function- Cell membrane structure hormones (chemical messengers)

Structure- Four interconnected carbon rings

Eicosanoids

Function- Chemical messaging

Structure- formed from arachidonic acid

Examples

Prostaglandins: Hormone, causes contractions
Leukotrienes: Inflammatory mediator

Deoxyribonucleic Acid (DNA)

Function- Information storage and code for protein synthesis

Structure- Double-stranded helix

Sugar- Deoxyribose

Paired bases-

Ribonucleic Acid (RNA)

Function- Carries out code for protein synthesis

Structure- Single-stranded helix

Sugar- Ribose

Bases-

Nucleic Acids

Monomers: Nucleotides

Pentose sugar- Deoxyribose or Ribose
Phosphate Group
Bases
Adenine
Thymine (DNA only)
Guanine
Cytosine
Uracil (RNA only)

Examples

Deoxyribonucleic acid- A double stranded helix with deoxyribose as the sugar, base pairs are A-T and G-C; encodes or protein synthesis.

Ribonucleic Acid- a single strand with ribose as the sugar, bases ae A, U, G, C; it carries out the code for protein synthesis.

How to properly hold a microscope: Use on hand to hold it by the arm and your other hand to hold is by the base for support.

You set the stage height by turn the big dial where my hands are front and back to raise or lower it.

Interphase

The resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.

Prophase

The chromosomes condense and the nuclear envelope breaks down

Metaphase

The chromosomes align at the equator of the cell.

Anaphase

The sister chromatids separate and move to opposite poles of the cell.

Telophase

The chromosomes decondense and the nuclear envelope reforms

Basic microscopy is important for A&P students because some organisms are so small, they can only be seen with magnification and to learn the structure of cells and microorganisms
