1 Nutrisi Ternak Dasar: Karbohidrat
Oleh: HARTUTIK

2 Pre-test Apa yang dimaksud karbohidrat?
Apakah hewan/ternak mampu mensintesis karbohidrat? Ya/tidak Sebutkan 3 pembagian/klasifikasi karbohidrat jika dipandang dari aspek nutrisinya? Kenapa karbohidrat penting bagi tubuh ternak? Gambarkan struktur kimia dari glukosa dan mannosa? Bagaimana cara analisis karbohidrat? Bagaimana karbohidrat dimetabolis oleh ternak ruminansia dan non ruminansia? Kumpulkan!! Bagi yang merasa tidak dapat menjawab dengan baik 5 dari 7 pertanyaan diatas, catat kembali soal ini dan kumpulkan sebagai tugas terstruktur?.

3 Carbohydrates: Include a large group of compounds which chemically are hydroxyaldehydes or hydroxyketones and their derivatives. In most instances, they are only sparingly soluble in organic solvents but highly soluble in water. This is of great advantage for transport in the body fluids.

4 Konversi -- photosintesis 6CO2 + H2O + 2870 KJ  C6H12O6 + 6O2
3 kelompok besar karbohidrat: 1. monosakarida 2. oligosakarida (2-8/10 sugar units) 3. polisakarida

5 C5H10O5 C6H12O6 (C6H10O5)n Penggolongan Nama Unit Analisis
Monosakarida Arabinosa Deoxyribosa Ribosa Xylosa C5H10O5 BETN Fruktosa Galaktosa Mannpsa Glukosa C6H12O6 Disakarida Laktosa Maltosa Sukrosa Galaktosa, glukosa Glukosa, glukosa Glukosa, fruktosa Trisakarida Raffinosa (C6H10O5)n Polisakarida Dextrin Glikogen Gum Pati Sellulosa Serat kasar

6 Monosakarida Hexoses CHO CH2OH CHO CH2OH CHO HCOH CO HCOH HCOH HCOH
HOCH HOCH HOCH HOCH HOCH HCOH HCOH HCOH HCOH HCOH CH2OH CH2OH CH2OH CH2OH CH3

7 Pentoses

8 Other monosaccharides
Glyceraldehyde (CHO-CHOH-CH2OH) Dihydroxyacetone (CH2OH-CO-CH2OH) the principal 3-carbon sugars (trioses) and are intermediates in the glycolytic pathway for the breakdown of tissue glycogen and glucose Small concentration with rapid turnover
