Protein catabolism (Krebs cycle) and Protein anabolism (protein synthesis)

By: HWC, Views: 8173

• Deaminated acids are brought into the Krebs cycle to be oxidized to CO2 and H2O. • Before entering the Krebs cycle, the deaminated acids are converted into intermediate products (pyruvic acid, acetyl coenzyme A, carbonic acids). • In the Krebs cycle, amino acids are oxidized to form r...

Four muscles—the supraspinatus, infraspinatus, teres minor, and subscapularis—make up the rotator cuff. It stabilizes the shoulder and holds the head of the humerus into the glenoid cavity to maintain the principal shoulder joint.

Protein Structure - Primary, Secondary, Tertiary and Quaternary

By: HWC, Views: 7656

A protein's first order structure, or primary structure, begins with the amino acid sequence of the polypeptide chain. The 20 different amino acids can be arranged in an infinite number of sequences. For example, the hormone insulin, which regulates the uptake of glucose from the blood into ce...

Structure of Amino Acid, Peptide Bonds & Polypeptides

By: HWC, Views: 7204

Here are the molecular formulas of three different amino acids. All amino acids share this backbone. The main difference between every amino acid is the side groups seen here, and these side groups give each of the amino acids their different characteristics. But before we get into that, let's ...
