 amino acids aren't stored in large quantities in (2) | blood or cells |
| cellular a.a are | polymerized into proteins needed by cells |
| a. a in blood may be used for energy. if used... | a.a. are replced by breakdown of protein in cells |
| excess a.a. stored | as fats or gycogen |
| deamination: occurs in | removing amino groups resulting in alpha ketoacid liver |
| alpha ketoacid can be converted to | intermediate of metabolic pathways |
| alpha ketoglutarate + NADH + amino acid ---> gultamate alpha ketoacid (convert to intermediate) | ... |
| to restore alpha ketaglutarate | gultamate + NAD + h2o --> NADH + alpha ketoglutarate + NH3 + H |
| need to keep NH3 levels low because.. | they stop cytric cycle |
| solution to NH3 | urea cycle in liver 2 NH3 + Co2 --> urea (secreted in urine) |
| energy potential of a.a. depends on... | which intermediate a.a. becomes |
| some a.a. converted to | acetyl coa then combined to ketone bodies to body cells |
| some a.a. are intermediates of CAC | ... |
| example of CAC | isoleucine become succinyl CoA |
| results | 1 NADH, 1 FADH2, 1 ATP |
